How i can move from jiujiang to changzhou or jiangyin?

There is one bus running daily at 17:10 from Jiujiang Long-distance bus station to Changzhou. It take a long time. There is no direct trian but it is easy to make a transit by train. You can take train from Jiujiang to Hefei and then take train from Hefei to Changzhou. The train journey is about 6 hours in total.
From Jiujiang to Jiangyin, you can take train from Jiujiang to Nanjing first and then take bus from Nanjing to Jiangyin.
